GAM Legacy Reports Are Gone: How Publishers Should Rebuild Reporting and Monitoring in 2026
If your team's scheduled Google Ad Manager reports quietly stopped running this spring, this is why: Google deactivated the legacy Reports tool on May 4, 2026, and Interactive Reports is now the only reporting interface in GAM. The migration isn't automatic - Google doesn't move your saved or scheduled reports for you, so any reporting workflow you'd built in the legacy tool has to be rebuilt by hand in the new one.
That's a chore. It's also an opportunity. Because you're rebuilding your reporting from scratch anyway, this is the cleanest moment in years to ask a better question than "how do I recreate what I had?" The better question is "what should our reporting and monitoring actually look like now?" Interactive Reports is a genuine upgrade for reporting - single-page exploration, AI-generated reports, and new notification flags. But flags are not a full monitoring layer, and the rebuild is the natural point to add one. This guide covers what changed, what to do about it, and where the line sits between what native GAM now does and what it still doesn't.

FAQ - The GAM Reports Migration
When was the GAM legacy Reports tool retired?
Google deactivated the legacy Reports tool in Google Ad Manager on May 4, 2026, completing a phased sunset that began in early 2026. Scheduled reports in the legacy tool had already stopped running on April 6. Interactive Reports is now the only reporting interface in GAM.
Does Google migrate my saved and scheduled reports automatically?
No. The migration is not automatic - Google does not move your saved or scheduled reports into Interactive Reports for you. You need to recreate the reports and re-schedule the exports you rely on by hand, which is why it's worth treating as a deliberate rebuild.
What does Interactive Reports add over the legacy tool?
Interactive Reports offers single-page report building, a metric and dimension search bar, charts, AI-generated reports, scheduled exports with Excel attachments, and notification flags. It covers the legacy report types, dimensions, and metrics that weren't formally deprecated.
Do Interactive Reports notification flags replace a monitoring tool?
For some teams, yes; for many, not fully. Native flags are a real improvement and operate at the report level. A dedicated monitoring layer adds a daily network-wide sweep, baseline-aware thresholds, severity triage that surfaces the worst issues first, and coverage organized around delivery, revenue, and inventory. The deciding factors are detection speed and how much direct-sold and programmatic volume you have to protect.
Should I add monitoring during the migration or after?
During is the efficient choice. You're rebuilding your reporting from scratch anyway, so the switching cost that usually blocks a monitoring upgrade is already sunk. Setting up reports, exports, native flags, and a monitoring layer in one pass is far less effort than revisiting it later.
